class_docstr: Interface for receiving logical document content events.
  
  This is the main callback interface in SAX, and the one most
  important to applications. The order of events in this interface
  mirrors the order of the information in the document.
docstr: Signals the start of an element in namespace mode.
  
  The name parameter contains the name of the element type as a
  (uri, localname) tuple, the qname parameter the raw XML 1.0
  name used in the source document, and the attrs parameter
  holds an instance of the Attributes class containing the
  attributes of the element.
  
  The uri part of the name tuple is None for elements which have
  no namespace.
